In our last 150 consecutive revascularization operations, 30 patients (20%) have had 4 or more bypass grafts. One patient died after quadruple grafting (mortality, 3%). Twenty-two (75%) of the survivors have been rehabilitated to active work status and 25 (86%) were considered by their cardiologists to have improved function postoperatively by New York Heart Association criteria. Preoperatively 15 patients (50% of the group) had either a markedly diminished ejection fraction (EF) or extreme elevation in left ventricular end-diastolic pressure (LVEDP) or both. Complete revascularization, with resection of ventricular aneurysms when present, can be carried out successfully in a high-risk group of patients. Elevated LVEDP or diminished EF per se is not a valid contraindication to myocardial revascularization.
